TANK-TRUCK FAUCET.

Application led April 27, 1922. Serial No. 556,913.

This invention is more particularly intended for use on tanks for thedelivery of reiinedoils such as gasoline, coal oil and distillate.

There are numerous difficulties to be overcome in the operation ofvalves for this pui pose, such for instance as the leakage likely toarise from the excessive expansion and contraction which results fromthe use of faucets for delivering liquids of this character in hotweather, The faucet being usually exposed to the suns rays and thevolatile liquid such as gasoline tending tofrap1d cooling of the faucetwhen the gasollne flows therethrough and evaporates therefrom;furthermore the liquid is very penetrative and it is necessary that thejoints be tight in order to prevent the flow of the gasolinetherethrough, and it has been customary to lubricate the` faucet with asuitable liquid such as glycerine that is not subject to be cut by thegasoline or other like hydrocarbon, and a feature of this invention isthe construction of the Vvalve so as to maintain alubricating bodytherein in the most efficient manner.

Furthermore when the faucet is closed after-drawing liquid therethroughthe slot` in the plug of the faucet contains a portion of liquid whichexpands as the faucet heats up in the rays of the sun or otherwise andthis expansion causes a portion of the liquid to force its Way outthrough the joint, thus Washing away some or all of the lubricating filmin the joint.

An obj ect of the invention is to maintain a predetermined pressure forholding the valve plug in its seat and for protecting the lower end ofthe valve plug, and the means which fasten the plug in its bearing.

Another requirement for the delivery of gasoline in cities and towns isthat the faucet shall be locked shut in the absence of .the attendant.This is found necessary in order to prevent danger of conilagrations.

An object of this invention is to so construct the faucet that the samewill be automatically locked when the faucet is closed and the handleremoved to provide means whereby when the handle is in place, the faucetplug will be automatically released.

Another object is to so construct the lu-y bricant container thatforeign substances will settle into the bottom thereof and not pass intothe lubricating-channels; and also to so construct the bottom annularchannel that the metallic substance displaced from the contactingsurface of the casing and plug will settle into an annular depressio-nin the casing.

Another object of invention is to provide a faucet with a tapered socketin which is seated a movable tapered plug with means for continuouslymaintaining a pressure on the plug to firmly hold it seated in thesocket to prevent leakage; and to also hold the plug firmly in place toprevent oils such as gasoline or kerosene entering the lubricatin spacebetween the walls of the socket and plug to cut the lubricant iluid suchas glycer- 1ne. And in order to prevent an excessive cutting of thelubricant by the oils that inadvertently enter this space circular andvertical channels are connected and arranged so that the lighter oilssuch as gasoline or kerosene can pass upward through the heavierlubricant such as gl cerine and escape into the lubricating chamliieplug where means are provided for removing them when necessary.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detail description and the appendedclaim.

The accompanying drawing illustrates the invention.

r in the end of the The faucet 1 comprises a hollow casing 2 having athreaded end 3 that is adapted to attach to a discharge pipeof adelivery tank not shown, or if desired the faucet can be attached to anydischarge pipe that has substantially the same bore and thread as thefaucet.

The casing 2 is provided with upper and lower extensions 4, 5 throughwhichthere is a tapered bore to it a rotary plug 6 which is providedwith a passage 7,that is transverse to a passage 8 through the casing 2when the plug 6 is in closed position; the passages 7, 8 `register whenthe plug 6 is turned ninety degrees on its axis; and when in suchposition a passage 9 through the casing 2 is open so that liquid canypass through the faucet and discharge from a spout 10.

The spout 10 is inclined downward and provided with an exterior thread11 by which it can be connected to a hose, not shown. The spout 10 isalso provided with cross vanes 11, 12. that prevent a whirling movementof liquid as it discharges'from the spout.

The plug 6 is held in close contact with the inner wall of the casing 2and extensions 45'thereof by means of a tension spring 13 that isinterposed between'a washer 14 that abuts a shoulder 15 of thel'extension 5, and a washer`16 secured by a cotter pin 17 on a threadedextension 18 ofthe plug 6; spring 13 permits expansion and contractionof the plug 6 within the casing 2 and yet maintain a tight fit betweenthe contacting walls. A nut 19 is provided on the stem 18 for holdingthe washer 14 in contact with the shoulder 15 and a cotter pin 20 isprovided for holding the-nut 19 in an adjusted position.

The lower end of extension 5 is threaded to receive a nut 21 forenclosing and protecting the yielding means for holding the plu 6 withinthe casing 2. i

lteans are provided for lubricating the contacting walls of the casingand plug. In the upper end of plug 6v is a chamber l22 for a lubricant4preferably glycerine or other fiuidlthat resists the cutting action ofgasoline; and this chamber is fitted through an orifice normally closedby a screw plug 23.

Also in the top wall of the chamber 22 is a vent for overflow of liquid,andr this 'vent is open while the chamber is being filled; and isnormally closed by a plug screw 24.

In the inner wall of extensionv4 .is provided an annular recess thatnormally registers with a similar recess in the outer wall of the plug 6and when registering with each other these recesses form an annularchannel 25 that is circular in cross section; and this channel isconnected to the chamber 22 by Small ports26.

Near the lower end of the plug 6 is an 4an-l nular recess 27 that issemi-circular in cross section;and in the inner wall of the extensionsand adjacent to the recess 27 is a larger plug 6 and the larger portionof the ellipse is formed within the wall of the casing 2 so thatsediment or foreign substance entering'the annular channel 29, formed byrecesses 27, 28 will settle into the bottom of the recess 28 as bestshown in Fig. 8, in which the dots 28 indicate sediment. The chamber 22is so formed that it is of considerable depth below the ports 26 so thatsediment can settle in the bottom of the chamber and not pass betweenthe walls of the casing and plu to score and cut them.'

,'Ilhe annular channel 25 is connected to the annular channel 29 bychannels 30, 31 and 32, 33 that are respectively cut in the contactingwalls of casing 2 and pllg 6; and the channels 30, 31, and 32,' 33,respectively, register with each other when the faucet is closed, thatis, the channel 30 registers with channel 31 and channel 32 registerswith channel 33 as best shown in Figs. 4 and 6; and these channelslubricate the contacting walls when the plug 6 is turned either to openor closed position.

Also it is obvious that lighter oils than glycerine can pass upward andescape into chamber 22 if inadvertently they enter the lubricating spacebetween the socket and pllglghe plug 6 is turned in the casing 2 to movethe passage 7 into and out of register with the` passage 8 by means of ahandle 34 that has a shank 35 adapted to extend into a .socket 36 of aside extension 37 that is integrally connected to the top end of theplug 6.

' In the bottom Wall of the extension 37 is a slot 38 nin which ispivoted on pin 39 a gravity dog 40 that has aheavy 'end 41 adapted tofall into a a side extension 43 of the casing 2 and locks the plug 6from further rotation when said plug has been suflciently moved to -fullclosed 'I )ositionfv and the handle -34 removed". That is, plug 6 hasbeen moved tofull closed position and the shank 35 is removed from thesocket 36, such removal of the shank releases the dog 40 and permits theheavy end 41 thereof to prevents the plug 6 from being turned until theheavyend 41 of the dog 42 is raised out ofthe recess 42 and this' isdone by inserting the shank 35.`

Means are provided for holding the dog in locking position after thehandle .is reenter the recess 42 and thus recess 42 formed in moved, andcomprise a key actuated plunger so that the. heavy end 41 can not bedisengaged from the slot 42 by insertion of the shank or its equivalent;and with this arrangement theplug 6 can not be turned until they dog isreleased by unlocking the plunger .44. The plunger 44 and operating lock45 can he of any desired construction.

The pur se of the dog latch is to hold the p ug 6 in fully closedposition to comply with ire ordinances; and the lock connected therewithto prevent nonemployees or unauthorized persons from removing oil fromthe tank to which the faucet is connected.

The assage 7 is enlarged at its discharge end 44 y cutting away aportion of the side' wall so that practlcally all the gasoline canescape from the passage as the valve is closed; that is the narrower orinlet end 46 of the passage is entrel covered by the casing wall to shuto the supply of gasoline before the enlarged or outlet end 44 isentirely closed or covered by the casing Wall; so that the gasoline inthe passage can fully escape to spout 10, as illustrated by dotted linesin Fig. 5.

In Fig. 4 the circular arrows indicate the direction of movement to openthe valve and in Fig. 5 they indicate the closing movement.

The full opening and closing movement of the valve is 90 degrees asindicated by the` arrow and dotted lme in Fig. 1; and in Fig. 7 themeans for limiting this movement is shown. As seen therein the top endof theY that consists of upper and lower spring rods 51, 52 that aresecured in the casing 2 by means of pinch nuts 53; and these rods areprovided with oppositely disposed hooks 54, 55 for extending throughholes inthe ends of a metal tag 56 on which is designated the contentsof the tankwith which the faucet is connected.

The tag 56 is placed on the hooks 54, 55 by springing the rods 51, 52toward one another until the hooks can be inserted through holes in theends of the tag; after which they are released and ytheir spring tensionwill then hold the tag firmly in lace.

The purpose of the tag 56 is to in icate the ynature of the liquid withwhich the faucet is connected so that .an operator will know positivelywhat liquid he is handling; and so that he will not easily mistakehighly explosive liquids for less combustible oils, and thereby preventaccident.

I claim: v n

TheV faucet set forth comprising a casin having a passage therethrough;a tapere plug in said casing having a passage therethrough that isnormallytransverse to the passage through the casing whenythe plug is ina fully closed position; a handle for actuatingv said plug to move thepassage therethrough into register with the passage through said casing;a chamber in said plug adapted to contain a lubricant; ports in saidplug leading' from said chamber, an upper annular channel communicatingwith said ports, an annular channel in the lower end of said plug,longitudinal channels formed in said plug and casing connecting the saidupper and lower channels and means for with-holding sediment from saidchannels.

In testimony whereof, I have hereunto set m 15th ay of April, 1922.
